I haven't been to Houston. But, people living in Singapore (near the equator) take public transportation and walk. So do people in Japan where it also ridiculously hot and humid. Japan also has just as many if not more rainy days than Houston and Singapore has double. I'm not saying I get why people would not want to walk. Only that it's common to do so anyway.
